CN2645850Y - Diameter altering honing knife - Google Patents

Abstract

The utility model relates to a diameter altering honing knife for the machining workpiece inside diameter, wherein, a guide groove is arranged on the front end of a tool bar 1 with a common straight shank or a taper shank along the axial direction of the tool shank, a regulating mass and a whetstone are embedded in the guide groove, and the whetstone can do radial movement by adjusting the position of a mandrel. The utility model can be used on various machine tools and can be provided with a plurality of guide grooves according to the diameter of machined elements, i.e. a plurality of regulating masses and honing whetstones. Therefore, the surface finish quality of the inside diameter is improved up to more than 0.4; the cooperation of the regulating mass and mandrel makes the honing whetstone do the radial movement along the tool shank in the guide groove to machine inside hole surface with different sizes. With strong commonality, low cost and convenient machining, the utility model is suitable for the honing of inside circle with coarse inner face and the diameter ranging from 10-400 mm, the diameter altering of a single-tool up to 40mm.

Description

The reducing honing knife

Technical field: the utility model relates to a kind of reducing honing knife that is used for the processing work internal diameter.

Background technology: each manufacturing enterprise is more to product inner bore surface roughness method for processing aborning at present, but the product inner bore surface roughness is reached Methods such as grinding, grinding, honing are below generally arranged, process tool be generally with processing parts in the cutter of the corresponding diameter of diameter of a circle, both a cutter was to a kind of processing of part of size internal diameter.The structure of cutter is the honing knife that handle of a knife combines with the oilstone of fixed dimension.

Summary of the invention: the purpose of this utility model is, but a kind of honing knife of reducing is provided.The technical solution of the utility model is, at the front end of common staight shank or taper shank knife bar 1, along handle of a knife axially offer gathering sill 9, be bumped in the gathering sill 9 and adjust piece 5, the outside of adjusting piece 5 is a deep trouth, embed oilstone 6, inner face is and the axle 4 corresponding step conical surfaces that knife bar 1 is an one with plug piece 7, the axle 4 of band step taper is inserted at knife bar 1 center, stage clip 2 is equipped with in the upper end of axle 4, and the lower end is put one and adjusted screw 8, between honing stone 6 and the knife bar 1 extension spring 3 is housed.The utility model has been changed in the past, and honing knife can only use on special purpose machine tool, and one cutter can only limit the use of in the situation of single size part, can on various lathes, use, the utility model can be offered a plurality of grooves according to the diameter of part to be processed, a plurality of adjustment pieces and honing stone both can be installed, therefore, improved the bore area fineness of processing parts greatly, product bore area fineness has been improved cause

More than, cooperate with the organic of axle owing to adjust piece, make honing stone in groove, to move radially along handle of a knife, finish the processing of different size bore area.Circular diameter was from the honing of the interior circle of the rough inner surface of 10～400mm in the utility model was applicable to, the reducing scope of hilted broadsword can reach 40mm, and versatility is extremely strong, and cost is low, processes easy.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

The shank of knife bar 1 is that the Mohs cone cooperates with lathe and joins, the other end is the straight-bar that has endoporus, a plurality of gathering sills 9 are radially arranged on straight-bar, what of gathering sill 9, the internal diameter size that depends on part to be processed, stage clip 2 is packed in the straight-bar of knife bar 1, to adjust piece 5 again packs in the groove 9, have two step inclined-planes below the adjustment piece 5, match with the axle 4 that has two tapering steps, honing stone 6 embeds in the groove of adjusting piece 5 outsides, be positioned at the lower end of knife bar 1 for the plug piece 7 of one with knife bar 1, the endoporus of plug piece 7 is a screw thread, the screw thread of plug piece 7 matches with adjustment screw 8, change the position of adjusting screw 8, axle 4 can be moved axially under the effect of stage clip 2, axle 4 contacts under the effect of extension spring 3 with two inclined-planes adjusting piece 5, thereby driving adjustment piece 5 and honing stone 6 moves radially, increase or reduce the diameter of honing knife, satisfying the processing of different size inner diameter hole, and, because the effect of extension spring 3, adjust piece 5 and be limited in effectively in the knife bar 1, the unlikely adjustment piece 5 that makes detaches knife bar.

Claims (1)

1. reducing honing knife of forming by knife bar, oilstone, it is characterized in that, the front end of knife bar (1), axially offer gathering sill (9) along handle of a knife, be bumped in the gathering sill (9) and adjust piece (5), the outside of adjusting piece (5) is a deep trouth, embed oilstone (6), inner face is and the corresponding step conical surface of axle (4), knife bar (1) is an one with plug piece (7), and the axle (4) of band step taper is inserted at knife bar (1) center, and stage clip (2) is equipped with in the upper end of axle (4), the lower end is put one and is adjusted screw (8), between oilstone (6) and the knife bar (1) extension spring (3) is housed.
